Abstract: Generally for any new design initially a concept layout in 2D CAD is generated. But sometimes, if the geometry of the product becomes complicated, then 3D CAD model is preferred, because 3D CAD model can give us a complete all side view at a time like a real product, but in a virtual world. The present case study will show the utilisation of 3D CAD at the concept design stage of a complicated shaped product for a new system. This will also give an idea about cost and time comparison. This will also show how 3D CAD model can also helps to analyse the product. Thus, this paper will describe about the importance of 3D CAD tools for product development.

Keywords: computer aided design; 3D CAD; computer aided manufacturing; CAM; product development; 3D software; 3D modelling; finite element analysis; FEA; conceptual design.
